THE BENEFITS OF RUMEN-PROTECTED METHIONINE FOR TRANSITION COWS
The transition period is one of the most challenging stages in a dairy cow's production cycle.
As nutrient demands increase and feed intake declines around calving, cows face significant metabolic and physiological stress.
Rumen protected methionine has been shown to support liver function, feed intake, immune response, reproductive performance and calf development during this critical period.

REHYDRATION REDEFINED: Smarter Electrolyte Support for Scouring Calves
Dehydration is a major risk in calf rearing, especially when scours strike. Calves can lose up to 10% of body weight in fluids within 24 hours, placing them at immediate risk of metabolic acidosis, growth setbacks, and even mortality. Effective treatment requires more than just fluid replacement. HYDRA-TRAC’s new formula reflects the latest understanding of calf physiology and electrolyte therapy, supporting rapid rehydration and flexible feeding alongside milk for a timely,

ADVANCING EARLY CALF NUTRITION: The Two-Stage TRAC Calf Supplement Program
Feeding whole milk to calves makes sense in some dairy operations; however, whole milk does not meet all the calf’s nutritional requirements with key vitamin and mineral gaps impacting growth and immunity. The TRAC Calf Supplement range bridges this gap. This tech tip article explains a two-stage program, that supports early development through to weaning for stronger, healthier calves.

FEED QUALITY BEYOND THE EYE: Managing Mould, Yeast and Mycotoxin Risk
When buying hay or silage produced under less-than-ideal conditions, livestock often respond differently depending on feed quality. Rain-affected hay, silage exposed to air, or poorly stored by-products can develop high levels of mould and yeast. Even when feed appears and smells acceptable, these contaminants may still be present at levels that reduce palatability and intake. As a result, animals may eat less, leading to declines in milk, meat, and wool, and potentially impa

PERENNIAL RYEGRASS TOXICOSIS (RYEGRASS STAGGERS)
Perennial ryegrass toxicosis (PRGT), more commonly known as Ryegrass Staggers, can be a serious problem in livestock grazing perennial ryegrass pastures during the summer and autumn months. It is most commonly seen in sheep and cattle, but horses, deer and alpacas are also susceptible. To help reduce the risk of Ryegrass Staggers, TRAC Performance Minerals loose-lick supplements (Flock Boost and Bovine Boost) can help manage some of the challenges associated with Ryegrass Sta

KEEPING WATER BELLY AWAY: HOW AMMONIUM CHLORIDE PROTECTS YOUR SHEEP
Urinary calculi (also called “water belly” or stones) involves the formation of phosphate-based stones in the urinary tract, which prevent urine flow. Left untreated, these blockages can cause the bladder to rupture and result in death. Young wethers are particularly prone to the condition. One of the simplest and most effective ways to prevent the problem is to correct the calcium to phosphorus ratio and include a small amount of ammonium chloride in the ration.

UNLOCKING DAIRY HERD POTENTIAL: THE CRITICAL ROLE OF MINERALS IN MILK PRODUCTION AND COW HEALTH
Achieving high milk yields, such as 8,500 litres per cow, requires meticulous attention to nutrition, especially regarding mineral and protein reserves. The primary focus for these high-producing cows is to build and maintain tissue and muscle reserves. These reserves serve as a “bank” during critical periods, such as calving and peak lactation, enabling cows to reach their production potential and get back in calf promptly.

BUILDING LAMB PERFORMANCE FROM THE INSIDE OUT
With harvest now behind us and confidence returning to the lamb industry, many producers are turning their attention to rebuilding numbers and lifting on-farm productivity. After navigating challenging seasonal conditions, now is an ideal time to revisit some of the fundamentals of “The Engine Room” — the rumen.

HEAT STRESS hits earlier than you think
With one of the coldest starts to summer on record, it feels almost ironic to be writing about heat stress—but warmer weather will arrive, and when it does, our cows will feel it quickly. Nutrition 101 tells us that a cow begins to experience heat stress when the heat generated by the cow is greater than the cow can lose through the environment. This often begins around 25°C but can be brought on at lower temperatures with high humidity.

SAY GOODBYE TO BITING FLIES WITH TPM BOOST FLY GO
Biting flies are a persistent challenge in dairy systems, contributing to cow stress, disrupted feeding behaviour, and inefficiencies in the dairy. Summer 2023/24 trials were conducted across SA and Vic to evaluate a new nutritional approach: TPM Boost FLY GO, a garlic-based supplement formulated for inclusion in dairy mineral mixes. The trials set out to measure its effectiveness in reducing cow irritation and improving herd behaviour, with promising results now ready to sha

2025-26 Hay & Silage Expectations
It’s been a tough fodder season, with floods up north and dry spells down south making quality hay and silage hard to secure. Testing forage with A1 Plus this year is essential to spot fermentation issues, fibre digestibility challenges, and spoilage risks before they impact animal performance. Contact Forage Lab Australia to discuss the best test options for your fodder this season.

The Importance of Sodium in Ruminant Production Systems
Earlier this year, TRAC Ruminant Productivity Expert Eliza Mackereth released a technical paper exploring why salt, a primary source of sodium, is one of the simplest yet most critical nutrients in any ruminant’s diet. While her analysis zooms in on dairy, the insights are equally valuable for anyone running beef or sheep enterprises.

GRASS TETANY: A Hidden Risk as Pastures Take Off
Grass tetany occurs when a cow’s magnesium intake or absorption drops below her daily needs. Lush, fast-growing feed is the classic risk because it is low in fibre and high in potassium, nitrogen, and water. High-magnesium loose licks will prevent problems from occuring.
